A Review of CO2 Laser-Mediated Therapy for Oral Mucosal Lesions

(1) Background: Several studies investigating the clinical outcomes of potentially premalignant oral epithelial lesions treated with CO2 lasers have been published over the last decades. (2) Methods: A systematic research review was performed for studies published between 2011 and 2021 in the PubMed, Science Direct, and Google Scholar databases. (3) Results: Initially, the search identified 52 relevant articles. The primary analysis of the titles and abstracts eliminated 22 articles, leaving 30 articles whose full texts were examined. A total of 22 articles met the inclusion criteria. The studies were classified into 3 categories. (4) Conclusions: After evaluating the results of all the studies included in this review, an initial general statement can be made, namely that CO2 lasers are a treatment option worth taking into consideration when approaching oral mucosal lesions. When compared to other types of lasers used in dental practice, the CO2 laser stands out due to its many advantages.
